Aluminum Processors in Henan to Suffer Tough Winter Output Controls  

Research originating from Dartmouth College showed that aluminum-based reflectors can help improve Wi-Fi signal coverage. By using 3D-printed reflectors coated with aluminum foil, researchers increased signal strength in targeted areas by about 6 dB while reducing unwanted signal leakage by around 10 dB. The principle is based on aluminum’s ability to reflect radio waves and redirect wireless signals toward desired areas. Although the popular “aluminum foil Wi-Fi hack” seen online is only a simplified version, the research demonstrated practical potential for aluminum reflectors in wireless signal management and future communication applications.

Alcoa shares climbed sharply as LME aluminum prices reached their highest level in four years amid concerns over potential Chinese production cuts and continued Middle East supply disruptions. On May 26, LME three-month aluminum prices rose to USD 3,682/t, while the cash offer price reached USD 3,759/t, the highest level since March 2022. Alcoa shares increased from USD 71.38 on May 22 to USD 74.57 on May 26, gaining about 4.5%. Markets remain focused on possible output restrictions at Chinese smelters linked to energy and environmental inspections, while Middle East tensions continue to tighten global aluminum supply expectations.

US rare earth companies are attracting stronger investor interest after the Trump administration launched “Project Vault,” a strategy aimed at strengthening domestic critical mineral supply chains and reducing dependence on foreign rare earth sources. Under the plan, the US government will directly invest in selected domestic rare earth companies through financing support from the US Export-Import Bank and measures linked to the Defense Production Act. USA Rare Earth has become one of the main beneficiaries, with investors focusing on its upcoming magnet manufacturing operations. Rising demand from EVs, defense and AI data centers is also increasing the strategic importance of rare earth supply security.
